Refund of bus fares

hi
I don't understand why must every ezlink card holder goes to MRT station to check if they are entitled to any bus fare refund. Since ezlink office knows which card is entitled to refund, cant they just automatically credit the refund into these affected ezlink cardholders? A simple computer programme can do this job.

Ezlink already over-charge... why make any mistake by troubling every Singaporean ? A waste of productivity! It is not right to donate un-claim $$ to charity. We should demand better service from our service providers. If they make mistake they should refund and compensate us.
